Anti-slip nuts for cable trays

Anti-slip nuts for cable trays include spring nuts, channel nuts, unistrut nuts, flange nuts, and specialized locking nuts designed to prevent loosening under vibration or load.

Main Types of Anti-

Slip Nuts

Spring NutsDesigned to slide into channel slots and lock in place with spring tension. Materials: Carbon steel, stainless steel, aluminum, fiberglass. Applications: Ladder trays, solid-bottom trays, wire mesh trays; suitable for heavy-duty and industrial installations.

Variants: Long spring, short spring, T-shaped, square designs. Channel Nuts (Unistrut Nuts)Fit into strut channels and pair with bolts for secure fastening. Sizes: M6, M8, M10, M12.

Features: Anti-rotation design, available in carbon steel or stainless steel, often with zinc or powder-coated finishes. Applications: Supports cable trays, ladders, and other modular support systems.

Flange Nuts

Provide a larger bearing surface to distribute load and reduce loosening. Commonly used with round head screws or bolts in tray assemblies. Materials: Zinc-plated steel, stainless steel.

Locking Nuts / Anti-Vibration NutsInclude nylon-insert lock nuts or serrated flange nuts to resist vibration-induced loosening. Often used in high-vibration environments such as industrial plants or offshore installations.

Specialized Cable Tray Nuts

Square splice washers with integrated nuts for connecting tray sections. Grounding clamp assemblies with integrated nuts for secure electrical bonding.

Considerations for Selection

Material: Choose based on environmental exposure (stainless steel for corrosion resistance, carbon steel for indoor use). Tray Type Compatibility: Ladder, solid-bottom, wire mesh, or trough trays may require specific nut designs. Load and Vibration: Anti-slip or locking features are critical in high-vibration or heavy-load applications.

Standards Compliance: Ensure nuts meet UL, DNV-GL, ABS, or other relevant certifications for safety and durability.

Summary

For comprehensive cable tray installations, the main anti-slip nuts include spring nuts, channel/unistrut nuts, flange nuts, locking nuts, and specialized splice or grounding nuts. Each type is available in multiple materials, sizes, and configurations to suit different tray types, load requirements, and environmental conditions. Manufacturers like T&Y Hardware, Platt Electric Supply, and Oglaend System provide extensive product lines covering these variants.
